[Coco] Calculating large numbers using string functions

[K. Pruitt]

A while back a discussion was had here on the list concerning calculating 
file sizes under Basic09.

I found a little file listing in the December 1984 issue of Hot CoCo which 
can large numbers, negative or positive, using the CoCo's standard string 
functions. This method could be easily adapted for use in Basic09 to 
calculate large file sizes.

The issue is available in the color computer archives.
